Shared library

Shared library for both back and front end.

Types

For a methods param, if its type references an enum/interface etc defined in a package, then the associated 'types' package needs to be in 'dependencies' and not 'devDependencies'.

This is because when typescript transpiles the code it will include that package in the 'd.ts' file. When mftb-shared is later installed, the package will be referenced. If its in dependencies it will be installed, if its in devDependencies it wont be installed and you will get a typescript error in the project that consumes mftb-shared

Eg:

import jwt from "jsonwebtoken";

const signToken = (
  payload: any,
  secret: string,
  algorithm: jwt.Algorithm
): string => {
  return jwt.sign(payload, secret, { algorithm });
};

Because jwt.Algorithm is used as a param type, we need to put the types package in dependencies. ie

npm install @types/jsonwebtoken <-- correct

NOT

npm install --save-dev @types/jsonwebtoken <--- wrong
